FAQ

What you need before your first validation

Answers on Telegram registration, balance, API access, and failed validations.

What does TG Validator verify?

TG Validator verifies whether a phone number is registered on Telegram. The product code is tg and it returns synchronously in the same HTTP response.

How is balance charged?

Balance is charged only for completed checks. It is purchased once with no subscription and is refunded if the check fails or the result is undetermined.

How do I get the $0.10 trial balance?

Create a free account, then contact support to claim your $0.10 trial balance for Telegram registration checks — or top up anytime.

How do I call the TG Validator API?

Create an API key in Settings, then POST to /api/v1/check with the X-API-Key header, a phone number in E.164 format, and service_type=tg. The endpoint returns a synchronous JSON response.

Does a registered result mean I can contact the number?

No. A result reports Telegram registration status at the time of the check. You remain responsible for consent, recipient preferences, and applicable platform rules before contacting anyone.
